Doty was last seen at 4:30 a.m. Sunday at a party at the Granada Boulevard duplex, where authorities say he got into an alleged physical altercation and then went missing until friends assisting Highlands County Sheriff's Office deputies found his body more than 30 hours later.

Along with second-degree murder, the two are facing charges of abuse of a dead human body and tampering with physical evidence, according to the Highlands County Sheriff's Office.

No other warrants are out at this time, authorities said, and more suspects may be charged as the investigation continues.

Investigators are still probing the sequence of events from the alleged fight to when Doty's body ended up in the woods, said sheriff's office spokeswoman Nell Hays.

"Everything after that (physical altercation) gets muddy," she said. "It's still under investigation."

Hays said she couldn't say if Rodriguez or Felipe were involved in the alleged fight but pointed out the two are not facing battery charges, which might change as the investigation proceeds.

Doty's dad had received a text message from his son's phone telling him that "Aaron had been involved in a fight," Hays said. Authorities are still investigating who else could have been involved in the reported brawl, Hays said.

Sheriff's deputies are interviewing everyone who was at the party and anyone who may have any information. Hays strongly advised anyone with any information to call the sheriff's office or Heartland Crime Stoppers, where tipsters are guaranteed anonymity.

When Doty's dad did not hear from him by noon Sunday, the family tried looking for him on their own, Hays said, and then alerted authorities a couple of hours later.

The sheriff's office did aerial surveillance of the Sun 'n Lake neighborhood Monday morning and then set up a command post.

According to HighlandsCounty Jail records both Rodriguez and Felipe have been charged with felonies before.

Felipe, who was released from jail in April, had been charged with battery causing bodily harm in February, along with charges ranging from possession and use of drug equipment, disorderly conduct in a public place, possession of a controlled substance without a prescription, burglary with assault or battery and possession of marijuana the same month.

Earlier in the year, he faced charges of disorderly conduct and resisting an officer, jail records show.

Rodriguez had been charged with probation violation in 2011, grand theft and burglary of an unoccupied dwelling in 2010, along with burglary of a conveyance, larceny and trespassing in 2009, records show.

Hays said authorities are following leads on their whereabouts. Sheriff's deputies have had no contact with the two since the search and investigation began.
